OpenStack for Architects

Overview of this book

Over the last five years, hundreds of organizations have successfully implemented Infrastructure as a Service (IaaS) platforms based on OpenStack. The huge amount of investment from these organizations, industry giants such as IBM and HP, as well as open source leaders such as Red Hat have led analysts to label OpenStack as the most important open source technology since the Linux operating system. Because of its ambitious scope, OpenStack is a complex and fast-evolving open source project that requires a diverse skill-set to design and implement it. This guide leads you through each of the major decision points that you'll face while architecting an OpenStack private cloud for your organization. At each point, we offer you advice based on the experience we've gained from designing and leading successful OpenStack projects in a wide range of industries. Each chapter also includes lab material that gives you a chance to install and configure the technologies used to build production-quality OpenStack clouds. Most importantly, we focus on ensuring that your OpenStack project meets the needs of your organization, which will guarantee a successful rollout.

Provisioning workflows

We've spent almost the entirety of this book discussing how to implement OpenStack and very little of it discussing how most organizations are actually using it. In this section, we'll explore different ways that OpenStack adopters typically provision virtual infrastructure. First, we'll look at giving users access to the Horizon user interface. Then, we'll look at provisioning through the Nova, Cinder, and Neutron APIs. Finally, we'll look at using Heat to orchestrate the OpenStack infrastructure using templates.

The Horizon user interface

The Horizon dashboard UI provides an intuitive and standardized interface for users who already understand the concepts of cloud computing and want to have complete control over their provisioned infrastructure. The dashboard works particularly well in situations where the end user is expected to provide some level of support, where they are responsible for scheduling their own backups, for example. We've seen this approach used in...
